Answer:
B.
Step-by-step explanation:
Step 1: Cross-multiply
x² + 2x = 4x²
Step 2: Isolate <em>x</em>'s
2x = 3x²
0 = 3x² - 2x
Step 3: Factor
x(3x - 2) = 0
Step 4: Find roots
x = 0, x = 2/3
Step 5: Double check answers.
When you do so, you should see that only x = 0 works. And we have our answer!
Answer: y=24
Step-by-step explanation:180-49=131 131-32=96, 96 devided by 4 is 24
What the regression is a conflict
If the volume of cube x divided by the volume of cube y is 27, then <span>he side length of cube x divided by side length of cube y would be 3. This is computed by solving the cube root of 27, since the side of the cube was multiplied thrice to get the volume so when geeting the side of the cube it is best to have the number be in cube root form.</span>
W = 2L / 3 and 2W + 2L = 50. Substitute 2L / 3 for W in the second equation to get:
<span>2(2L/3) + 2L = 50 </span>
<span>4L/3 + 6L/3 = 50 </span>
<span>10L/3 = 50 </span>
<span>L = 3 * 50 / 10 = 15. Replace L for 15 in the first equation: </span>
<span>W = 2(15) / 3 </span>
<span>W = 10</span>
